Human Heart Anatomy Diagram - Labeled Cross-Section for Medical Education #3540213 (License: Personal Use)

This medical illustration presents a sagittal cross-section of the human heart with distinct color coding: red for oxygenated blood pathways (e.g., left atrium/ventricle), dark maroon for deoxygenated blood (right side), green for the septum and valve structures, and blue for the superior/inferior vena cava. The image clearly depicts the mitral, tricuspid, aortic, and pulmonary valves, as well as the interventricular septum and myocardial wall layers.

Used in educational resources, anatomy textbooks, medical websites, and patient education materials to explain cardiac structure and function; matches user intent for learning or reviewing heart physiology and pathology basics.
